Consider the Voltaic Cell Based on the Following Reaction: Zn(s) $\to$

question 19

Multiple Choice

Consider the voltaic cell based on the following reaction: Zn(s) + Ni²⁺(aq) $\to$ Zn²⁺(aq) + Ni(s)
Two students are assigned to measure the standard cell potential at 25°C.Student one claims that both solutions of ions have to be at exactly 1.00 M concentration,but student two is sure that the measurement will be the same if the concentrations of the two solutions are equal,but not necessarily 1.00 M.What do you think?

• A)Student one is right because,by definition,standard cell potentials must be measured at concentrations of 1.00 M.
• B)Student one is right because she understands the Nernst equation and what it describes.
• C)Student two is right because she understands the Nernst equation and what it describes.
• D)Student two is right because cell potentials do not depend on the concentration.
• E)Both are right because cell potentials do not depend on the concentration.

Definitions:

Vesicular Follicle

A fluid-filled structure in the ovary that contains a maturing oocyte (egg) during the menstrual cycle.

Primordial Follicle

Primordial follicles are the earliest stage of ovarian follicles, consisting of a primary oocyte surrounded by a single layer of flat granulosa cells, and represent the initial pool of potential ova in females.

Secondary Follicle

A stage in the development of ovarian follicles where the follicle grows in size and begins to secrete estrogen.

Primary Follicle

An early stage in the development of an ovarian follicle, characterized by a single layer of granulosa cells around the oocyte.
